>> reporter: with cheers from his crew and tears from his mom, daredevil felix baumgartner began his improbable journey to the edge of space. >> capsule, check, are you ready? >> reporter: for 2 1/2 hours, the 43-year-old austrian skydiver floated to an astounding 24 miles up, 128,000 feet above the new mexico desert where he opened his capsule, hung his feet out the door, was reminded to unfasten his seatbelt, saluted, and he just jumped right into the record books. he plummeted at an incomprehensible 833 miles an hour, so fast, the only way to see him in this infrared camera. the first human to break the sound barrier with just his body, no jet, no rocket. he tumbled out of control for a few tense seconds, then righted himself and managed to make a sound. it was enough for mom. >> okay, here we go, felix.
